Petunia surfinia

Information and generalities

Ascribed to the genus Petunia, this hybrid, obtained in Japan during the second half of the eighties, depopulated in gardens and terraces thanks to the abundant and continuous flowering. The parent species of the hybrid are Petunia violacea and Petunia nyctaginiflora, both native to Brazil and also widely distributed in the world for ornamental purposes. Surfinia looks like a bushy, drooping plant with long green and intricate stems. The leaves are large and round, dark green, covered with a sparse and soft down, typical of the genus. The flowers are bell-shaped, large and with petals welded together, with a texture reminiscent of velvet or silk. They bloom from late spring to late autumn, with purple, fuchsia, red, pink or white varieties. There are also

The varieties of Surfinia

Petunia Surfinia, in turn, has many varieties selected artificially, which modify the color of the flowers and the posture. Common above all on the flowered terraces is the «blue veined» Surfinia, called in this way due to the blue or deep purple veins that radiate the petals, which in turn are lavender. The «pink veined», on the other hand, is characterized by candy pink petals inlaid with dark pink veins, although this variety is less common than the previous one. Particularly sought after for flowers that vaguely resemble those of vanilla, the «yellow» and «lime» Surfinia have much larger flowers than the other varieties, with colors ranging from creamy white to canary yellow. One of the latest varieties imported into Europe is the «purple picotee»

Plant the Petunia Surfinia

Although it is possible to plant some petunia species via seed, Surfinia is a hybrid that produces unusable seeds as they are sterile. It successfully reproduces by cutting, which is done in autumn, by taking a sprig without flowers of about 10 centimeters from the mother plant. It should be planted in a well-drained soil, partly made up of river sand or peat, kept constantly humid and taking care to place it in a shady area. After rooting, when the plant has reached 20 centimeters in height, it is possible to plant it in a larger pot or in the garden, exposing it in an area where there is enough sun for at least 8-10 hours a day. Surfinia requires little care, if not a constantly humid (but never soggy) substrate and fortnightly fertilization with potassium-based products,

Petunia surfinia: Pruning and tips

During flowering, which occurs in summer and ends in late autumn, dried flowers and leaves must be removed; in fact they represent the main vectors of powdery mildew, a disease that causes the yellowing of healthy leaves and stems, slowly leading the plant to decay. True pruning is often carried out in summer, when the adult plants reach considerable size and the apical stems, which last receive the nutrients, begin to yellow. With the help of well-sharpened and sterilized shears, the branches are eliminated by shortening them by at least two thirds. This way, the plant will benefit by producing new, stronger branches. Another factor to take into consideration is exposure to bad weather, since petunias are irreparably damaged in strong winds; for this reason,
